Where is the fuse for the sofa bed?

My 1995 Chevrolet conversion van has a fuse panel behind the driver seat built into the wall next to the passenger captain seat. This fuse panel is dedicated to the conversion package installed into the van. My van has a small wooden door or it could be a panel that can be removed that matches the interior of the van. Since there are many different companies that covert vans the fuse panel could be anywhere in the interior body of the van. You most likely will not find conversion package fuses under the hood. Also try looking under the sofa bed.
